Java

Dies ist ein informelles Treffen für Lernende, die ihre ersten Schritte in der Programmierung machen oder ihre Grundkenntnisse vertiefen möchten. *** This is an informal meetup, for learners that want to do their first steps in programming or want to consolidate their skills. We spend one hour and a half working on tutorials, exercises or projects. If you need help to get started, we will help you finding a good way for learning. You should be prepared to spend your time "doing things": just hanging around and listening might get boring, if all other people are learning on their side. There are experienced people are around and you can ask questions as soon as their arise or bring with you questions you have had during the week. During the last half an hour, we do a (simple) exercise together. We speak German, English, and a few other languages. Currently, how main programming languages are: * Python * Javascript * Java * Flutter * C++ * C * C# * PHP But you're free to learn any programming language during our Co-Learning! If you want to learn more about our Co-Learning, please have a look at our website (no frequent updates...): https://opentechschool-zurich.github.io/ If you're starting with Python, we can suggest: * Learning Python the hard way (https://learnpythonthehardway.org/python3/) (for Python 3). * The Solo Learn Python 3 Tutorial (https://www.sololearn.com/Course/Python/). * A big list of Python tutorials: https://docs.python-guide.org/intro/learning/ For Node.js: * Nodeschool: https://nodeschool.io/ For C++ * https://de.wikibooks.org/wiki/C%2B%2B-Programmierung * https://www.sololearn.com/Course/CPlusPlus/

Anybody who wants to practice their programming skills is welcome. We share our ideas, learn from each other, do some exercise, ask questions, etc. This meetup is the best for those who want to improve their skills by programming and learning in a group If you want to learn more about our Co-Learning, please have a look at our website: [https://opentechschool-zurich.github.io/](https://opentechschool-zurich.github.io/) \*\*\* We have a chat group you can join to get more information: [https://app.element.io/#/room/#ots-zh:matrix.org](https://app.element.io/#/room/#ots-zh:matrix.org) (You need to create a free account if you don't already have one) Remote participants are also welcome.

**Sponsored by:** ***\- ACP*** ***\- TD SYNNEX*** ***\- Technopark Winterthur*** **Partner-led and partner-branded by**: ***Microsoft*** Speakers: * Firas Cheaib (ACP) – When Models Become the Commodity * Victor Chibotaru(LogicStar AI) – Shipping Faster, Drowning Sooner Abstract: When Models Become the Commodity ACP Engineering works extensively with LLMs to write production code across a small team. What makes that work is not the models, but the groundwork laid before them: a portfolio of Python projects sharing the same tooling, structure, tests, CI, and linters, the same conditions that already made the codebase easy for humans to navigate. That foundation is what powers the current build of ACP-M, ACP's industrial IoT platform for manufacturing customers, and an early agentic-loop prototype now running internally. The next step is enabling customers to automate their own operations the same way. Doing that requires the same kind of preparation on their side: turning fragmented operational data into knowledge graphs, unified namespaces, and typed semantic layers, so that agents act on information that is short, focused, and reliable. Once that environment exists, the model becomes a commodity. What matters is enterprise processes and domain knowledge, not which model happens to be in fashion that quarter. Attendees will leave with a concrete way to assess whether their own environment is ready for agents at all, and what it takes to get there -- Shipping Faster, Drowning Sooner AI ships your features faster than ever, but it also ships bugs faster than ever. Code got cheap, maintenance didn't: customer complaints stack up, Sentry alerts overflow, and triaging the pile is still as expensive as it ever was. I'll show how LogicStar finds bugs across your Sentry, Jira and codebase, separates signal from noise, and helps your team fix issues that matter.

**🚀 JavaScript Luzern Meetup** Hey everyone! We're planning for another evening of frontend goodness. 📋 What's on the agenda? **Coding the coder: how coding agents work - Hugo Sousa** You’ve probably already tried or are using on a daily basis a coding agent, such as Claude Code, Codex, OpenCode, Pi, etc. But perhaps you’re not aware of how they work. What is a coding agent? What does it take to build one? In this talk I’ll dig into the internals of coding agents and what it takes to build a minimal one. **The Browser Is Your Framework - Mateusz Halada** Let’s explore how modern web applications can be built directly on the platform using HTML, CSS, JavaScript, and browser APIs - without defaulting to heavy frameworks. Through a live demo, we’ll recreate common UI patterns and show what frameworks actually abstract under the hood. We’ll also demystify concepts like SPA, SSR, and CSR to understand where they truly come from. The goal isn’t to replace frameworks, but to give you the clarity to choose them intentionally—and know when you don’t need them. **Coding Atrophy: What Software Engineers Can Learn From Aviation - Maximilian Walterskirchen** Aviation spent 30 years figuring out that automated cockpits were atrophying pilot skills. The data on AI coding tools is starting to look uncomfortably similar. A talk on what aviation figured out, what the research shows, and the bug that made me realize my own skills had gone soft. 🎤 Call for Speakers! We still have open slots and would love to hear from you! If you've been working on something interesting — whether it's AI-related or any other JavaScript/CSS topic — reach out and share it with the community. Not sure what to talk about? We can help suggest a topic based on your interests. First-time speakers are absolutely welcome! Food and drinks are on us. A big thank you to [CSS](https://www.css.ch/) for providing the location! See you there! 🙌

Welcome to the Competitive Play Session. This session takes place every Saturday from 10:45 to 12:15 at the Yonex Badminton Hall Hardbrücke.

New players and those who are new to badminton are welcome to join the PM Session (Open Level Play). Payment can be made via TWINT after the session.

Web Zurich presents inspiring talks all about the web. Join us for the Mai 2026 meetup! We will have three talks as well as chit-chat and drinks. Whatapp: [https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK](https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK) Website: [https://webzurich.ch](https://webzurich.ch) 18:30 \~ 19:00 Arrival time with drinks, chat 19:00 \~ 19:10 Welcome and introduction 19:10 \~ 19:30 *Alex Suzuki* **Monetizing JavaScript: Building Profitable Products as a Solo Developer** Lessons learned from building and launching a commercial JavaScript library as a solo developer. 19:30 \~ 19:50 *Hugo Sousa* **Ten times tea** I'm building a programming language. When I got to the frontend, I ran into a problem: React's mental model is elegant, but the mental model is at odds with the code. Hooks, effects, and render passes create a runtime that bears little resemblance to the code we write. The Elm programming language works differently and its architecture (TEA = The Elm Architecture) has been adopted by other tools over the years. So I copied it as well. My language embeds TEA at the language level, not as a library. This unlocks time-travel debugging, reproducible application state and serializable bug reports that include the entire program state. This talk covers the quick introduction of my language, TEA, why TEA is the right fit and what becomes possible when the architecture is baked into the language itself. 19:50 \~ 20:10 *Marco Gähler* **Software testing** Many old software projects don't have any tests - if the code works, why should you bother with tests? Well, you really should bother, because code changes all the time. During development, you keep adding new features which at times requires large scale modifications of the code that will inevitably alter existing functionality. And in existing projects, one still has to make updates once in a while, for example for security patches. These things will always break existing functionality and tests are the only remedy against this issue. In this talk, we will look at the basic idea of tests, how to implement them, what issues to look out for and how you can test pretty much any piece of code if your code base is well structured. 20:10 onward More drinks & chat We look forward to see you there!

Model Context Protocol (MCP) is emerging as a standard way for AI models to securely interact with external tools and systems. This session provides a practical deep dive into MCP architecture, core concepts, and real-world integration patterns. We will explore how MCP enables structured tool calling, improves interoperability, and simplifies AI integration in existing applications. The talk will include examples of connecting AI models with APIs, databases, and enterprise systems, with a focus on how developers can adopt MCP in Java-based environments. **Note**: This is a hybrid in-person/online event. Food and social for those in the OCI training room starts at 6:00pm. Presentation starts at 6:30pm for those online and in the training room.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
